We’re less than a week away from Super Tuesday, when roughly a quarter of the Republican delegates will be up for grabs. Reliable polling is still remarkably hard to come by for many of the 11 states voting on Tuesday, but by now it should come as no surprise which Republican is the favorite to have the best day: Donald J. Trump.

The next Republican presidential debate is Saturday in Greenville, South Carolina, a state that promises an unpleasant race to the finish line. There was a GOP debate in Charleston just last month. CBS News hosts this meeting; it ran a Democratic debate in Iowa in November.

CNN’s Wolf Blitzer will moderate tonight’s Republican Debate on CNN, the final opportunity for the crowded field to debate in 2015. Dana Bash and Hugh Hewitt will also be involved asking questions of the candidates, who will be split into undercard and primetime debates.

Coverage of the fifth Republican debate will begin at 8:30 pm Eastern tonight on CNN. But don't worry, if you don't have cable, you can still tune in — CNN will generously post an online livestream available at CNN.com. Coverage of the earlier undercard debate will begin at 6 pm Eastern. (The actual debate segments, however, might start a bit later than these stated times — CNN has been vague about when, specifically, the debate itself will kick off, and will likely lead in with commentary. The main event will probably start around 9 pm.)

Watching the Republican presidential hopefuls slug it out for the last time in 2015 will be easy, thanks to a free livestream from of Tuesday’s debate in Las Vegas. CNN, host of the fifth GOP debate of the cycle, will make a stream available on their homepage at CNN.com and on the network’s mobile apps. Coverage starts at 5 p.m.

With the Republican establishment’s anguish rising along with the ascent of Donald Trump and Ted Cruz, Tuesday night’s debate could be the most dramatic yet, coming just 48 days before voters have their say in Iowa. All eyes, as ever, will be on Trump. The real estate mogul is polling at his highest level of the 2016 race, even after — or perhaps because of — remarks about Muslims that his rivals have denounced. Party higher-ups, however, remain uncertain about how, or whether, to wage a concerted effort to destroy him.

When is the next Republican presidential debate? The fifth Republican presidential debate will be Tuesday, Dec. 15th, live from The Venetian in Las Vegas. It will be hosted by CNN and Salem Radio. What time and how long is the debate? The first of the night’s debates – the undercard forum – starts at 6 PM EST, which means the prime time session doesn’t begin until 8:30 EST. A CNN spokesperson says details on formatting are to come, though one network announcement notes that the web stream of the debate lasts until 11 PM EST.

Here we go again. On Tuesday, CNN will air the latest episode of this season’s blockbuster reality show—also known as the Republican primary debate. And, yes, Donald Trump is coming despite an earlier threat to stay away unless the network paid him $5 million to appear.

Fox Business Network hasn’t exactly been subtle about its plan to make Tuesday’s Republican presidential primary debate better than the last one. Here’s the script of a 10-second promo for the event in Milwaukee: “CNBC never asked the real questions, never covered the real issues. That’s why on November 10, the real debate about our economy and our future is only on Fox Business Network.”

Ben Carson and Marco Rubio will try to maintain their momentum while several once-formidable candidates battle for survival at the fourth Republican presidential debate of the campaign on Tuesday night. The debate, taking place in Milwaukee and hosted by Fox Business Network, comes at a critical time in the 2016 race.

The fourth Republican debate will air at 9 pm Eastern tonight on the Fox Business Network. But don't worry, if you don't have cable, you can still tune in — Fox Business will generously post an online livestream for all at FoxBusiness.com. This is in contrast to the last GOP debate hosted by CNBC, which had a livestream restricted to people with cable accounts.

Debates are the new currency of presidential campaigns. The first three Republican presidential debates have drawn record audiences. At least so far, they’ve done more to affect the candidates’ standings than millions of dollars spent on field organizations and TV ads. Now the GOP hopefuls are slated to meet again Tuesday night in Milwaukee. Here are six things to watch.

Fox Business Network is arranging for a broader audience of cable and satellite customers to have access to its broadcast of the Republican presidential debates Tuesday. Distributors that charge extra for Fox Business – including DIRECTV, Suddenlink, Mediacom, Frontier, Wide Open West, Cable One, as well as several smaller carriers in the National Cable Television Cooperative – have agreed to “unbundle” the channel, making it available to their entire subscriber bases for the debates.

Fox Business Network, the host of Tuesday’s GOP debate, has its claws out — not for the candidates, as its moderators vow to stick closely to the issues, but for its more famous competitor CNBC. Tuesday’s encounter will be the first Republican debate since CNBC’s on Oct. 28, after which multiple campaigns blasted the moderators for losing control and asking “gotcha” questions — while Republican National Committee Chairman Reince Priebus dismissed it as a “crap sandwich.”

When Maria Bartiromo and Neil Cavuto kick off Fox Business Network’s debate on Tuesday evening, they’re going for one thing more important than ratings. They want the Republicans running for the White House to offer specifics. The business duo will guide the conversation for the relatively new network—it launched in 2007—as back-to-back debates take place in a Milwaukee theater. The lesser-polling candidates will kick things off with an undercard debate, while the eight top-polling contenders will face-off in primetime.

Thirteen Republican presidential campaigns had started the week in a kind of solidarity, brainstorming ideas to make the cable news debates more fair. They ended the week in pathos and disarray, after Fox Business announced that two candidates would be shunted from prime time to an "undercard" debate, and two mainstays of the undercard debate would not make it to the Nov. 10 forum at all.
